### Earth’s Place in Space

Unit 12, Section 1

• Earth rotates around its axis every 24 hours.

D

• ROTATION 1 Day = 24 Hours

Y

• One revolution of the Earth around the sun takes a year.

S

• REVOLUTION 1 year to complete

N

• The seasons change because the Earth’s axis is tilted.

• When the northern hemisphere faces the sun, we have summer.

• At the same time, south of the equator is facing away from the sun, so they are in winter.

• The Moon orbits around Earth once every 27.3 days.

• The light on the moon comes from the sun.

• When we see the moon completely lit, it’s called a full moon.

• The time while the sunlit part gets larger is called a waxing moon.

• When none of the moon is lit, it’s called a new moon.

• The time while the sunlit part gets smaller is called a waning moon.

• The moon is between the Earth and the sun, blocking our view of the sun.

• Not all of the Earth will see a total eclipse.

• The Earth is between the moon and the sun.

• Only happen during the full moon.
